SEEDMASTER 2023
15
Wing-Down pressure may need to be increased if the wings start to float and not contour correctly while
in the seeding position or if a positive Wing-Up pressure is detected.
Wing-Down pressure may need to be decreased if the wings become too rigid while in the
seeding position.
RAVEN (METER) SUPPLY PRESSURE: 2000 psi
LIFT KIT: 200 psi
FAST WING PRESSURE: 1500 psi
SAFETY SHIFT VALVE: The safety shift valve will shut the hydraulic flow off to the block if back
pressure reaches 240 psi on tank line to prevent system damage.
PRESSURE SETTING PROCEDURES
Setting Wing-Down Procedure (WING-DOWN PRESSURE)
The Wing-Down pressure is the amount of hydraulic pressure being applied to the inner and outer wing
circuits; the oil supply is supplied from the system pressure. The Wing-Down Pressure is required so the
wings will contour while travelling through the field. SeedMaster requires Net Wing-Down Pressure. To
determine your net value, subtract your wing-up pressure from your current wing-down pressure (
ie.
380
PSI wing-down – 200 PSI wing-up = 180 PSI net wing-down).
- To adjust the WING-DOWN PRESSURE, loosen the jam nut on the cartridge in port WD on the
main block. Turn the cartridge in to increase the pressure, and out to decrease the pressure.
When the desired pressure is set, re-tighten the jam nut.
Setting Wing Unfold Procedure (FAST WING PRESSURE)
The wing unfold pressure is the amount of hydraulic pressure being applied to the inner and outer wing
circuits while the tool bar is unfolding. This is also known as the Fast Wing Pressure. If the wings are not
unfolding the pressure will need to be increased. The oil supply is supplied from the system pressure.
- To adjust the FAST WING PRESSURE, loosen the jam nut on the cartridge in port FW PRESS
on the main block. Turn the cartridge in to increase the pressure and out to decrease the
pressure. When the desired pressure is set, re-tighten the jam nut.
Active Wing Brace Check
The Active Wing Brace supports the wing
sections of the frame. While in the field, a
hydraulic cylinder pulls the rear of the wing
section forward counteracting draft while
seeding. The hydraulic pressure comes
from the opener cylinder hydraulic circuit.
The higher the pressure is set to the active
wing brace circuit, the more it will pull the
rear wing square. When the packing
pressure is increased, so is the amount of
pull on the brace to a set maximum.
- Adjusting the wing brace: Start
by unfolding the SM drill and
activating the system pressure.
Next, pressure the openers down with the opener pressure switch and adjust the shank down
hydraulic pressure to 1000psi, activating the active wing braces. After the system has been
completely pressurized, inspect each wing brace cylinder indicator. They should be fully
retracted against the plate limiter. If not, please adjust the length of the active wing brace using
the threaded link. The braces should be periodically checked to ensure proper adjustment. This
will ensure your frame integrity remains true and helps increase the longevity of your machine.
Meter Drive Pressure Setting Procedure (RAVEN METER SUPPLY PRESSURE)
The Meter Drive Pressure is the amount of hydraulic pressure allowed to the hydraulic metering drives.
The torque to the metering drives increases as the pressure increases. Do not exceed 2200 psi. The oil
supply for RAVEN METER SUPPLY PRESSURE is supplied from the system pressure.
- To adjust the RAVEN METER SUPPLY PRESSURE, loosen the jam nut on the cartridge in port
RAVEN on the main block. Turn the cartridge in to increase the pressure and out to decrease
the pressure. When the desired pressure is set, re-tighten the jam nut.
